Economic difficulties restricted production at the Danuvia Factory, and while most developments remained at the prototype stage, only the DMV-125 (DMV: Danuvia Modified Version) started serial production. These modifications, however, were only small exterior changes, and were very easily recognisable. They centred upon a revised shock absorber, different shape saddle and an overall grey finish (although different colours were also available). The more developed 4-speed, 7 horsepower model did not go into mass production.
